Abstract:
      The nylon 66（PA66）short fiber was modified by grafting of vinyl trimethoxysilane（coupling agent KH171 ），and the properties of KH171 grafting modified PA66 short fiber/natural rubber （NR） composites were studied. The results showed that the grafting modification of PA66 short fiber with KH171 improved the interfacial adhesion between PA66 short fiber and NR. Compared with unmodified PA66 short fiber/NR composite，the modulus and tear strength of KH171 grafting modified PA66 short fiber/NR composite increased obviously，and the maximum increase was obtained when the mass fraction of KH171 solution was 0. 15，and the peak of the loss factor of the composite was reduced.
